SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 349,980, dated September 28, 1886.

Serial No. 196,514. (No model.)

To @ZZ w/Lom it may concern:

Be it known that I, SAMUEL J. CLARK, a citizen of the United States, residing at Bunker Hill, in the county of Miami and State of Indiana, have invented certain new and useful Improvementsin Spring Bed-Bottoms; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had tothe accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The ordinary spring bed-bottoms are objectionable since when two persons of different weight occupy the same bed, the heavier per son dcpresses his side of the bed to a greater extent than the lighter person, the consequence being that the lighter person rolls down against his co1npanion,which is uncomfortable In order to overcome this objection it has been proposed to make the bed-bottom in two sections, and to place a greater tension upon one section than the other. This, however, is only a partial and ineffective remedy, since it only answers where the same persons occupy the same bed, and would evidently be impractieable for use, for example, in a hotel.

Another proposition has been to make the bed-bottoni in three longitudinal sections of canvas of equal width, ljoined together along their adjacent edges. This does not, however, overcome the objection completely, since the heavier person will depress his side sufiiciently to depress also the center section, and so enable the lighter person to still roll down against him.

The present invention is an improvement on these constructions, and consists in a bed-bottom composed ot' three longitudinal sections of woven wire unconnected with each other, the two side sections being of equal width, and the centerl section being a narrow one and stretched to a greater tension than the side ones. This center section divides the bed into two independent portions, and interposes an insuperable barrier to the persons from rolling together.

Aside from this main feature, the invention also consists in an improved construction of the frame which supports the woven-wire seetions.

The invention is illustrated in the accornpanying drawings, in which Figure l is a plan View of the bed-bottom. Fig. 2 is a vertical cross-section in the plane indicated by the line l l in Fig. l, and Fig. 8 is a side View of one end of one of the side rails.

rIhe supporting frame-work consists of two side rails, A A, and two end rails, B B, between which latter rails the three sections C C D of woven wire are stretched. rIhe side rails are placed edgewise, and the end rails are laid horizontally and secured to and between the side rails with their upper surface at about the vertical centers thereof, as seen in Fig. 2. This construction is important, since it enables much lighter material to be used for the rails, and the side rails reaching above the rails B B, retain the mattress when placed on the springs which extend along the center ofthe rails A A.

I make no claim to the prior constructions hereinbefore named; but

\Vhat I claim as my invention is- A spring bed`bottom composed of three longitudinal extending sections ot' woven wire un connected with each other, the centersection being much narrower than the side ones and stretched to a greater tension, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

SAMUEL J. CLARK.
